PROGRAMMING CONTROLLER PARAMETERS THROUGH EXTERNAL TERMINALS OF A POWER CONVERTER

摘要

This relates to systems and processes for programming parameters of a controller of a power converter. In one example, a predetermined signal may be applied to the input or output terminals of the power converter to unlock the controller and cause the controller to enter a programming mode. While in the programming mode, one or more additional predetermined signals may be applied to the terminals of the power converter to program one or more parameters of the controller. Once the desired parameters have been programmed, another predetermined signal may be applied to the terminals of the power converter to cause the controller to exit the programming mode and enter a locked mode. The predetermined signals applied to the terminals of the power converter can include an ac or dc signal having a predetermined pattern of changes in frequency, amplitude, and/or magnitude that are applied for a fixed or variable duration.

主权项

1. A method for programming a controller of a power converter, wherein the method comprises:
causing the controller to enter a programming mode by applying a first predetermined signal to one or more terminals of the power converter; programming one or more parameters of the controller by applying a second predetermined signal to the one or more terminals of the power converter; and causing the controller to exit the programming mode by applying a third predetermined signal to the one or more terminals of the power converter.
